How do scientists learn what babies know?
Babies learn language from the language (or languages) they experience in the world around them. But what is early language experience actually like for babies? Observational methods can give us a glimpse into children’s everyday lives – what they hear, see, and say.
One approach uses naturalistic recordings to understand child language development. In this approach, researchers collect audio- and/or video-recordings of babies (with parent permission, of course), trying to capture what speech they hear, what they say, and what goes on around them
